Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slat constituting a shutter curtain of a lightweight shutter, and more particularly to a slat of a window shutter.

[0002]

2. Description of the Related Art In a window shutter composed of slats that are externally attached to windows around the outer wall of a building and are continuously bound by an interlock, when opening and closing the shutters manually, a handle fitted to the slats is used. Means have been taken such that a finger is pulled down and pulled up and down, and an operation is performed by pressing a finger on an interlock portion of the slat.

[0003]

However, in such a conventional shutter, a hand-held slat had to be separately prepared in order to provide so-called hand-held parts. When the shutter is lowered by pulling the slat directly downward, the middle part other than the interlock is straight or curved. This is limited to the part that transitions from the part to the interlock part, and only a part of the fingertip is applied to such part, so that the burden on the fingertip has increased. In addition, the seat plate can be directly gripped and raised and lowered, but which part should be gripped depends on experience and intuition. In addition, as shown in FIG. 10, there is a case where the indoor has a protruding side at an intermediate portion in the height direction of the seat plate, but when the shutter is lowered with a fingertip on the protruding side, the lower end of the seat plate bends forward. In order to rub against the guide groove on the outside of the guide rail, more techniques were required. Even in the case of a motorized window shutter, the same operation must be performed at the time of a power failure or the like.

SUMMARY OF THE INVENTION [0004] In view of the above problems, an object of the present invention is to provide a shutter that can be easily manually operated by using components of a seat plate and a slat directly above.

[0005]

In order to achieve the object, a shutter according to the present invention is a shutter made of slats that are stitched in multiple stages by an interlock. While a horizontal protruding side is formed in the indoor direction, a protruding portion facing the indoor side is formed in an intermediate portion of the slat directly above the seat plate, and the horizontal protruding side is substantially the same as the indoor side tip of the protruding portion. Is characterized by the following configuration.
In this case, it is preferable that the upper surface of the projection has a horizontal surface.

[0006]

According to the present invention,
When the shutter is closed, the entire hand can be firmly pushed over both the projecting portion and the horizontal projecting side, so that the burden on the fingertip can be reduced. Because it is possible to use both the surface of the protrusion and the horizontal protrusion side,
As compared with the case where only the horizontal protruding side is pressed, the size of the horizontal protruding side in the indoor direction can be made as small as possible.
Since the horizontal protruding side is located at the upper end of the seat plate, the lower frame of the sash does not hinder the hand, and the shutter can be more easily closed. There is no need to prepare different slats that have been processed, and the parts to be processed can be omitted. Since the pressing by the fingertip results in the pressing of the protruding portion in the downward direction, the slat can be smoothly lowered to the guide groove of the guide rail. If the upper surface of the protruding portion is a horizontal surface, the above effects will be further enhanced.

FIG. 1 is a sectional view showing a closed state of a shutter, and FIG. 2 is a sectional view showing a seat plate and a slat immediately above. FIG. 3 is a perspective view showing the engagement between the seat plate, the horizontal protruding side and the guide rail, and FIG. 4 is a longitudinal sectional view of the shutter.

In FIG. 4, 1 is an outer wall of a building, 2 is a base material for attaching a sash frame, 3 is a sash frame attached to the base material 2 on the outdoor side of the building, and upper and lower frames 3a, 3b and left and right vertical frames 3c, 3
and 3d is a shoji. Reference numeral 4 denotes a shutter case provided above the sash frame 3, which is fixed to the outer wall 1 of the building with nails (or bolts) 6. The shutter case 4 includes a front case 4a, an upper case 4b, lower cases 4c and 4d, and a side case 4e. Reference numeral 5 denotes a bearing bracket. A winding drum 5b for winding a shutter is mounted on the bearing 5a.
The bobbin 5b is provided with a bobbin (not shown) that facilitates manual opening and closing.

Reference numeral 7 denotes a guide rail, which stands upright with the guide groove 7a facing the left and right vertical frames 3c, 3c of the sash frame 3. Reference numeral 8 denotes a drainer provided at the lower end of the guide rail 7, and the drainer 8 is a table plate portion 8 that slopes outdoors.
a, a tip drainer 8b, a fixed side 8c, and the like.
The drainer 8 is located below the sash lower frame 3b,
c is fixed to the outer wall 1 of the building with nails or the like.

Reference numeral 9 denotes a slat constituting a shutter curtain, and a lowermost slat 10 is a seat plate. Each slat 9 is provided with an upper interlock portion 9 for binding up and down.
a, a lower interlock portion 9b and an intermediate portion 9c.
A portion 9d that continuously transitions from the intermediate portion 9c to the lower interlock portion 9b forms a protruding portion that faces the front end portion 9e toward the indoor side, and extends over the entire area in the longitudinal direction of the slat 9, and the lower end of the intermediate portion 9c in cross-sectional view. Has a shape protruding toward the indoor side. Generally, the cross-sectional shape of the slat 9 is such that the intermediate portion 9c is flat or slightly curved toward the outside. Since the slats 9 that are continuously bound are inserted and guided in the guide grooves 7a of the left and right guide rails 7, 7 and rise and fall, the thickness dimension X1 of the slats 9 is regulated within the groove width dimension X2 of the guide groove 7a. As a result, the protrusion dimension of the protrusion 9d in the indoor direction is inevitably within the groove width dimension X2, and is such that only a part of the fingertip is applied. In this embodiment, the projecting portion 9d is provided at the transition portion to the lower interlock portion 9b. However, the present invention is not limited to this. For example, a plurality of projecting portions 9
Needless to say, d, 9d,... may be provided. However, in this case, it is desirable to provide an interval between the protruding portions 9d, 9d such that a fingertip enters.

The seat plate 10 has an interlock portion 10a which engages with a lower interlock portion 9b just above the slat 9;
It is composed of an intermediate portion 10b, an indoor draining portion 10c, an outdoor draining portion 10d, a lock attaching portion 10e, and a horizontal protruding side 10f. The horizontal protruding side 10f is located above the upper interlock portion 10a, and the distal end 9e of the protruding portion 9d and the horizontal protruding side 10f are positioned at substantially the same level. As shown in FIG. 1, at least the horizontal protruding side 10 f can have a fingertip placed on the protruding portion 9 d and the horizontal protruding side 10 f, and does not come into contact with the shoji 3 a and the sash frame 3. The specified dimensions are not required as long as they are within the range. Further, an upright side 10g may be provided in which the tip of the horizontally protruding side 10f in the indoor direction is further slightly raised. Note that a resin stopper (not shown) is attached to the outdoor side of the intermediate portion 9b to prevent the shutter from being caught in the shutter case 4. In order to prevent the upper surface of the horizontal protruding side 10f from slipping,
It can also be uneven.

In the shutter having the seat plate 10 configured as described above, when the shutter in the open state is manually closed, the following is performed. First, the indoor side drainer 10c of the seat plate 10 or the horizontal protruding side 10
The operator places his hand on f and slides the seat plate 10 downward by sliding the guide groove 7a. Along with this, the slats immediately above the seat plate 10 and the series of slats above the slats interlocked together are also lowered simultaneously. At a position where the seat plate 10 is lowered to some extent, the fingertip is pushed further downward without permission by pressing the protruding portion 9d and the horizontal protruding side 10f. Thus, the horizontal protruding side 10f is located on the indoor side above the indoor-side drainer 10c and also above the lower frame of the sash frame 3, so that the seat plate 10 can be easily pushed down to the table plate surface 8a of the drainer 8. Can be. In this state, the lock is automatically locked by a lock device (not shown) housed in the lock mounting portion 10e.

When it is desired to open the shutter, it is sufficient to push up the horizontal protruding side 10f from below and perform an operation substantially opposite to the above-described closing method.

FIG. 5 shows a second embodiment of the present invention and is a sectional view showing a closed state of a shutter. The present embodiment is different from the first embodiment in that the upper surface of the projection 9d has a horizontal surface. This makes it easier for the fingertip to hit both sides of the protruding portion 9d and the horizontal protruding side 10f, thereby making it easier to close the shutter.

FIGS. 6 and 7 show a third embodiment of the present invention, and FIG. 6 is a sectional view showing a closed state of a shutter. FIG. 7 shows the seat plate 10 and the horizontal protruding side 10.
FIG. 5 is a perspective view showing the engagement between f and the guide rail 7.
The difference between the present embodiment and the second embodiment is that the horizontal projection side 10f has a smaller protrusion dimension toward the indoor side and is within the groove width X2 of the guide groove 7a of the guide rail.
0 can be directly inserted into the guide groove 7a at both ends of the guide groove 7a without a notch (FIG. 7).

In this case, the shutter can be easily opened and closed as in the first embodiment.

FIGS. 8 and 9 show a fourth embodiment of the present invention, and FIG. 8 is a cross-sectional view showing a closed state of a shutter. FIG. 9 shows a seat plate 10 and a horizontal protruding side 10f.
FIG. 3 is a perspective view showing the connection between the guide rail 7 and the guide rail 7. The difference between this embodiment and the third embodiment is that the handle 12 is fitted to the indoor end of the horizontal protruding side 10f while keeping the horizontal protruding side 10f having the same size to the indoor side. It is what was worn. The handle 12 can be slid in the longitudinal direction of the seat plate 10 along the rising edge 10g.
Therefore, the size of the handle 12 in the longitudinal direction of the seat plate 10 only needs to be large enough to touch a fingertip. Of course, the dimension may be slightly shorter than the distance between the left and right guide rails 7. Further, as shown in FIG. 9, a small-width handle 12 can be attached or slid to a portion close to the guide rail. The material of the handle 12 is made of resin or aluminum.

In summary, the present invention is to secure an area corresponding to a handle between the protruding portion 9d of the slat and the surface formed by the horizontal protruding side 10f of the seat plate 10. It is possible to achieve a specific function and effect.
